AircraftPower vs Lightspeed App
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
AircraftPower
This app calculates and displays the performance of various aircraft engines. It offers a graphical representation of engine performance charts and allows users to input various parameters to see real-time output. Users can choose between English and metric units for measurements.
- Reciprocating engine performance model
- Calculates sea level and altitude performance
- Graphical engine performance chart
- Manual construction method illustration
- Input manifold pressure, RPM, altitude, temperature
- English and metric unit options

AircraftPower is an Aircraft Engine Performance App. It uses a standard reciprocating engine performance model to calculate and display the sea level and altitude performance of 74 normally-aspirated Continental® engines and 108 normally-aspirated Lycoming® engines. A graphic display shows the engine performance chart and illustrates the manual construction method for determining altitude performance that we learned in ground school (and promptly forgot). As the user changes the input values, using the sliders or the custom keypad, for manifold pressure (or % power), rpm, pressure altitude and outside air temperature, the power output and percent power (or manifold pressure required) are displayed, and dotted lines and colored dots in the graphic display follow the manual construction method. While the graphics aren't really necessary, they are instructive (and interesting) to watch. The user may choose english or metric units for altitude, altimeter setting, temperature, manifold pressure and power output (however, the graphic always uses english units), and may select default values for the inputs and the engine. The user can also choose to input the indicated altitude instead of the pressure altitude (the default), and choose to input the % rated power instead of the manifold pressure. If using the indicated altitude, an input window for the altimeter setting appears.

A companion app to the Lightspeed Delta Zulu ANR headset, the Lightspeed app for iOS features an array of integrated features to keep pilots and passengers safer during flight. Track CO Sensors for Safer Flying The Lightspeed app allows pilots to check the CO levels in the aircraft during flight, using a CO sensor built right into the Lightspeed Delta Zulu headset. The sensor provides real-time smart alerts via the proprietary Kanari™ smart alert technology. Historical data can be stored, reviewed, and analyzed after use and during the flight(s). Personalize Audio with HearingEQity™ The Lightspeed app introduces a built-in audio equalization system called HearingEQity™ designed to compensate for individual hearing loss. Through an automated 12-frequency hearing test taken through the app, HearingEQity sets the hearing level in each ear in a variety of frequency bands of the Lightspeed Delta Zulu headset to create an individual hearing profile and compensate for any hearing variations between ears. Record Conversations, Archive Flight Recordings, and More... The Lightspeed App allows pilots to record radio conversations, playback transmissions, draw diagrams, and archive flight recordings for post-flight briefings and training.

Verdict
The clearest difference is review sentiment: AircraftPower at 100% against Lightspeed App's 11%. AircraftPower also leads on rating (4.9 vs 3.3) and iOS requirement (13.5 vs 15.0). Lightspeed App's advantage is device support (3 vs 1) and ratings volume (54 vs 18). On price, update cadence, ads and in-app purchases there is nothing between them.
